Correlated stopping of relativistic electron beams in supercompressed DT fuel

Abstract

Fundamental features of dynamically 2-correlated relativistic electrons in the MeV energy range and interacting with very dense and hot hydrogenic plasmas of fusion interest are thoroughly investigated. The target is modelled with a Drudelike dielectric function. Longitudinal and undamped pair correlations along overall drift velocity are contrasted to transverse ones decaying exponentially over several tens of target screening length λ D. Other novel behaviours include a much higher response to target temperature variations, than to density ones, for the ratio of 2-correlated to uncorrelated stopping.
